Uniting Local Memory with Brand Devotion
A Cherished Neighbourhood Yakiniku Restaurant

In Ōizumigakuen — developed as a residential district before the war and still known today as one of Tokyo’s most liveable neighbourhoods — Heijoen has renewed its outpost along National Route 24.
Since its founding in 1970, the brand has been embraced by multiple generations, building its name on whole-cow wagyu and a tradition of quality and integrity.
A steadfast companion to everyday life, it grew through roadside locations designed for easy access by car, becoming a fixture of the community.
The renewal was conceived to ensure Heijoen remains the kind of place families bring children and grandchildren — a restaurant etched into family memory and treasured across generations.
The design draws on the land’s memory as a wooded grove. The entrance atrium, framed by walls inspired by traditional yoroi-bari siding and grounded by a stone-paved floor, evokes the outdoors. Restrained tones tighten the space, while overhead wooden louvres conjure the grove’s stillness and calm.
Material choices echo the brand’s whole-cow wagyu philosophy — solid cedar, hewn for the counter and integrated into artwork, infuses the interior with the timber’s inherent strength and warmth.
With wagyu at its core and a space intended to embrace all generations, the design reimagines traditional Japanese motifs through a contemporary lens. Drawing from the brand’s deep roots in the community, every last detail of Heijoen’s interior is imbued with the atmosphere and memory of its locale.
